SPECIFICATION forming part of Letters Patent No. 775,220, dated November 15, 1904.

Application filed May 12, 1902. Serial No 107,004. (No modeln To {1f/l 1071/0/11r 'if 72mg/ concern:

Be it known that l, HARVEYP. Joxns, a citizen of the United States. residing at Chicago, in the county of Cook and State of lllinois, have invented-a new and useful Improvement in Binders, of which the following is a specification.

My invention relates particularly to binders for loose-leaf ledgers; and my primary object is to provide a binder of this character of exceedingly simple construction, great strength and durability, and readiness of manipulation.

My invention is illustrated inits preferred embodiment in the accompanying drawings, in whiclr Figure 1 represents an inner view of the improved binder; Fig. 2, a section taken as indicated at line 2 of Fig. L1; Fig. 3, a similar section. but showing the binder extended; Fig. i, an enlarg'ed composite section taken as indicated at the lines 4 of Fig. 1; Fig. 5, a similar section taken as indicated at the corresponding lines of Fig. 1; Fig. 6, an enlarged broken section taken as indicated at line e' of Fig. l. and Fig. T a broken section taken as indicated at line T of Fig. 6.

The preferred construction is as follows: A represents the binder-back; B B, clamping members slidable transversely on said back; C C' and D D', oblique guides arranged in pairs on the clamping members; E, a rod disposed longitudinally of the back and equipped at opposite sides of its center with right and left threads; F F, nuts connected with the rod E and bearing rigidly-secured obliquelyset bars F2 F, provided with guide-engaging rollers a; Cr G, telescopic binding-posts connected with the free edges of the clamping members, and G Gr extensible binding-posts having' tongue-and-groove connection and serving to hold the leaves in proper position at all times.

The back A is provided on its inner surface at its ends with flanges 11, and adjacent to its ends are bridge-pieces (f, through which tlie rod E extends. The bridge-pieces fr are provided with outwardly-projecting members a2, which are supported some distance above the inner surface of the back. The clamping members are of general L shape, having for wardly-projecting portions and inwardlyprojecting portions V/1, The portions have the bindingposts connected with them at their free edges and are equipped with lugs lf", having perfor-ations for receiving the pivots of tbe cover-sections. 'l`hc portions of the clamping members are substantiallyY parallel with the back A and lit between the flanges f1v and the under surfaces of the members 11"'. The clamping members are provided at their ends with rudimentary flanges l1", the inner surfaces of which contact with the edges of the members ai.

The guides C C and l) D' comprise opentopped channels, as shown. Preferably the members of each pair of guides converge inwardly, and the inner ends of the guides are turned abruptly toward each other. T he bars or heads F2 F are preferably set obliquely, as shown.

The rod E is supported wholly by the nuts F F and is without contact with the bridgepieces d. One end of the rod is squared to receive a key c. As an added securityT against longitudinal shifting of the rod the rod may be provided with a circumferential groove c for receiving a pin c", passing' through one of tlie bridge-pieces ai'. The binding-posts (i comprise telescopic tubes of well-known construction. The binding-posts comprise half-tubular members connected with one clamping member and having inturned longitudinal flanges and pins le recessed to receive tlie members and form therewith binding-posts of substantially circular crosssection. The rollers a.' are preferably of the form of cone-frustums` so that their lower portions contact with the lower portions of the guide-channels in which they move.

The manner of use will be readily understood from the foregoing detailed description. Vhen the rod E is turned in one direction, it serves to draw the nuts F F toward each other, thereby forcing the rollers a along their oblique guides and separating the clamping members, and when said rod is turned in the opposite direction a reverse action occurs. The members of each pair of guides are set at an Obliquity which will cause the clamping members to move at the desired speed. Vhen the rollers a reach the inner end of the guides, they encounter portions of the guides having a greater Obliquity, and hence the clamping members are caused to move with greater rapidity. In practice the binder is never filled with leaves to the full extent of its capacity of expansion, some space being requisite to enable the leaves to be inserted or removed. After the first effort to release the clamping members from the leaves the clamping members move with much facility. The feature of the curved inner ends of the two sets of guides is therefore of considerable advantage in that the rate of movement of the clamping members is increased ata point where slight effort is required to move them.

It will be noted that the members of each set of oblique guides are somewhat staggered with relation to each other, the purpose being to permit the inner ends of the guides to pass each other to a certain extent, thereby enabling' the clamping members to approach each other more closely. This will be understood clearly from Figs. l and 2, where the inner ends of said guides are shown projecting over the rod E. In use separation of the back from the clamping members is impossible by reason of the manner in which they are connected, and racking is prevented by reason of the fact that the members a2 engage the inner surfaces of the flanges 6*. The clamping members therefore are guided accurately, so as to move transversely on the back. Moreover, the connection between the members of each pair of oblique guides tends to prevent racking of the parts.

The improved binder is one of exceeding simplicity for a binder of its character, and the binder possesses inherent strength and facility of operation. It readily will be understood that any suitable cover-sections may be supplied and that any suitable bindingposts may be employed in lieu of the bindingposts shown.

Changes in'details of construction within the spirit of my invention may be made. Hence no undue limitation is to be understood from the foregoing detailed description, which has been given fol clearness of understanding only.

Vhat I regard as new, and desire to secure by Letters Patent, is
